Here is more proof that Mary Sproul Logue was never married to John Lodowick Sprogell , M.M.G. of Pennsylvania. According to several old books, John Lodowick Sprogell of Philadelphia was married to a person named Mary. They had three children: Catherine, Lodowick, and John. However, Lod'k Sprogell (b.1709) died on October 8, 1781. If Mary was really born in 1770, she would have been only 11 years old at his death. I don't think that she was his wife. Even if she was older than this, what happened to their three children?
